Shrub rose plant named ‘AUSjive’

ABSTRACT

Shrub rose plant substantially as shown and described, characterized particularly by its flowers in deep, rounded, many-petalled cups of deep pink color; having an Old Rose fragrance on a rounded shrub with arching stems, medium to tall in size; and its resistance to powdery and downy mildew.

Genus and species: Rosa hybrida.

Variety denomination: ‘AUSjive’.

ORIGIN OF THE INVENTION

The present invention relates to a new and distinct variety of a shrub rose plant named ‘AUSjive’ which was originated by me by crossing an unnamed, unpatented seedling with an unnamed, unpatented seedling.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a very tough and healthy, repeat flowering variety with full, deep pink blooms on a rounded shrub.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

-   -   1. Flowers in deep, rounded, many-petalled cups of deep pink         color.     -   2. Rounded shrub with arching stems, medium to tall in size.     -   3. Old Rose fragrance.

Asexual reproduction of this new variety by budding, as performed at Albrighton, England, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

Comparison with Parents

The seed parent is a larger shrub than ‘AUSjive’ and has paler pink blooms. The pollen parent has scarlet, semi-double blooms compared with the full, deeply cupped, deep pink blooms of ‘AUSjive’.

Comparison with Similar Variety

‘AUStijus’ has blooms that are more lilac in color with smaller, narrower petals than ‘AUSjive’ and a fruity fragrance. ‘AUSjive’ has more deeply cupped, fuller blooms with an Old Rose fragrance and has redder prickles than ‘AUStijus’.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart (2001), except where ordinary dictionary significance of color is indicated.
